Drag and drop OS files into Webview

[matthewjamesadam]

I have a custom view (Webview) in a sidebar (WebviewView). I'd like the custom view to be able to handle drag and drop events, specifically file drag and drop (from the OS, ie file explorer).

I've implemented the standard HTML5 events, but these only seem to work when holding down shift. I'm curious if this is intentional or not -- it makes the functionality effectively impossible to discover.

Are there any alternatives to this?
